Abstract

Aims: Worsening renal function in patients undergoing percutaneous coronary intervention (PCI) for STelevation myocardial infarction (STEMI) is associated with adverse clinical outcomes. We hypothesised that platelet glycoprotein IIb/IIIa receptor inhibitors (GPI) may decrease the rate of renal function deterioration in these patients through attenuation of platelet aggregation and the possible improvement of renal rheology and haemodynamics. Methods and results: Based on prospectively collected data, we analysed rates of renal function deterioration in 603 consecutive patients (mean age 58±13 years, males 82%) with STEMI treated with primary or rescue PCI. Renal function deterioration was defined as an increase in serum creatinine level of ≥25% and/or ≥0.5 mg/dl at any time point post-PCI during index hospitalisation compared with baseline value. Outcomes were stratified by treatment with GPI. Patients treated with GPI (n=442) vs. patients who were not treated with GPI (n=161) had significantly lower rates of serum creatinine increase of ≥25% compared with baseline (22.9% vs. 31.9%, P=0.02, respectively), of serum creatinine increase ≥0.5 g/dL (4.1% vs. 8.8%, P=0.02). Treatment with GPI was associated with significantly lower mean maximal increase in serum creatinine level compared with baseline value (0.14±0.38 vs. 0.25±0.45 mg/dL, P=0.005). Rates of major bleeding did not differ significantly between the two groups (7.3% vs. 5.9%; P=0.42), while 30-day mortality was significantly lower in patients treated with GPI (2.3% vs. 7.5%; P=0.005). By multivariable analysis, treatment with GPI was an independent predictor of freedom from renal function deterioration (odds ratio 0.53; 95% confidence interval 0.33-0.86; P=0.01). Conclusions: In this analysis, administration of GPI to patients with STEMI treated with primary PCI was associated with lower rates of worsening renal function and lower 30-day mortality.
